Noise debunked as coming from missing Argentinian submarine

The worldwide search effort for the missing Argentine submarineARA San Juan will benefit from calm weather this week, and just in time: the sub's supply of breathable air is likely running low, according to the Argentine Navy.

"Special software is being used to study different sounds and acoustics", navy spokesman Enrique Balbi told reporters in Buenos Aires. Storms have complicated search efforts as relatives wait anxiously. The submarine had reported an electrical malfunction, before losing contact with authorities last Wednesday, in the South Atlantic, some 430 kilometers off the Argentine coast.

The submarine was heading from a base in southern Argentina's Tierra del Fuego archipelago to its home port in Mar del Plata. Authorities have mainly been scanning the sea from the sky, as storms have made it hard for boats.

Hopes for a successful search for the submarine waned when the navy said satellite calls detected over the weekend did not in fact come from the vessel.

A specialized USA aircraft had been sent to the area, about 225 miles east of the Valdes Peninsula in Patagonia, after the noise was detected by two Argentine naval vessels searching for the submarine.

At last contact with its naval base, the submarine had given word of a battery glitch, Capt. Gabriel Galeazzi, another spokesman, said.

Simmons also noted that the pair were together for two days and one night, but mainly in public or with other people present. Keri Claussen Khalighi told The LA Times in a Sunday report that she met the duo at a casting call in 1991 when she was 17.

"A warship has a lot of backup systems, to allow it to move from one to another when there is a breakdown", he said.

Argentine President Mauricio Macri travelled to Mar del Plata Monday morning, where the submarine's base of operations is located, to monitor the situation and support the families of the crew members on the missing submarine.

Among the 44 crew members is Eliana Krawczyk, the first female submarine officer in Argentina.

They were joined by President Mauricio Macri: "We continue to deploy all available national and global resources" to find the submarine, he tweeted. Morales and other relatives of crew members have been gathered at a naval base in Mar del Plata, where authorities are coordinating the search and rescue operation.

Intermittent satellite communications were detected on Saturday and the government had said they were likely to have come from the submarine.

The official said that crews of submarines in distress bang on the vessel's hull to alert passing ships to their location. It was built in Germany and in 2008 was brought to Argentina for maintenance which included the replacement of the electric propeller engines together with the four diesel engines, Reuters reports.
